Propagation of the Wigner function is studied on two levels of semiclassical propagation: one based on the Van Vleck propagator, the other on phase-space path integration. Leading quantum corrections…
Entanglement dynamics in open two-qubit systems via diffusive quantum trajectories.
- C. Viviescas, I. Guevara, A. Carvalho, Marc Busse, A. Buchleitner
- PhysicsPhysical Review Letters
- 8 June 2010
This work uses quantum diffusive trajectories to prove that the time evolution of two-qubit entanglement under spontaneous emission can be fully characterized by optimal continuous monitoring and derives a deterministic evolution equation for the system's concurrence.
Quantum theory of multimode fields: applications to optical resonators
- C. Viviescas, G. Hackenbroich
- Physics
- 13 October 2003
A recently developed technique for the system-and-bath quantization of open optical cavities is applied to three resonator geometries: a one-dimensional dielectric, a Fabry–Perot resonator, and a…

- 23 October 2017
By optimizing the squeezing parameters, the derive a family of Gaussian non-Markovian stochastic Schrödinger equations for the dynamics of open quantum systems and can tailor unravelings for improving entanglement bounds or for environment-assistedEntanglement protection.
Optimal dynamical characterization of entanglement.

- PhysicsPhysical Review Letters
- 7 May 2007
We show that, for experimentally relevant systems, there is an optimal measurement strategy to monitor the time evolution of entanglement under open system dynamics. This suggests an efficient,…
